How To Update LG Optimus 3D P920 with Ice Cream Sandwich Android 4.0 Firmware

Procedure to update Ice Cream Sandwich 4.0 on LG Optimus 3D:

  • First up you need to download the Ice Cream Sandwich 4.0 Firmware Zip to your computer. Once it’s downloaded, you will now need to proceed to connect the phone to the computer using the USB cable which you got at the time of purchase.
  • So, once you are done with the downloading, you need to copy this downloaded zip file as it to your phone without modifying or renaming the file. Once you copy the same, you now need to download the ROM Manager application in your phone.
  • The ROM Manager can be installed from the Android Market Place. Now, once you downloaded and installed the ROM Manager application, you need to open the same and then select the option of “Flash Clock Work Mod Recovery” to flash the same.
  • Once you are done with this, you now need to create a backup of your current ROM which you can do by selecting the option of “Backup Current ROM” in the ROM Manager so that you can then revert back to the Stock original version just in case if you face any issues with the new Ice Cream Sandwich ROM as its in the beta stage.

ROM Manager backup Restore

  • After this select the option of “Install ROM from SD Card” and then you will have to choose the zip file of “IceCREAMSandwich4.0_for_LGOptimus3D_KingROM” after which the process of the firmware update will be commencing.
  • After a period of around 5 – 8 minutes, the firmware update process will be finished and then you will see that the device will be restarted on its own, if not then you need to select “++++ Go Back ++++” to get back to the main menu and then choose to “reboot system now” to restart the phone.
  • Just in case if you are facing issues like the Force Close errors then you need to select the options Wipe data/factory reset, Wipe Cache partition and then choose reboot system now to restart the phone and to enjoy this all new firmware.

Do let us know just in case if you face any issues in the comments section below as we will try our level best to help you. So, in this way you have easily updated your LG Optimus 3D smart phone with the latest version of Android Ice Cream Sandwich 4.0 version.

    I did all steps mencioned here, step by step, or from begin to the end. The diference that I saw is all pictures posted on this website is very very diferent from the phone, I do not why.

    I agree with Vortecduramax, Bara 93, tyler wewsecv, almost said the same thing, I just don’t know what is wrong with KING 3D ROM, even I cannot find out its official website. Now, my phone is broken ’cause of it. It does not power on anymore.

    I’ll send it to Lisbon, Portugal, to be repaired for free without any fee/charge/fare.

    I just wish much luck for who has it on phone and it runs normally, my best.

      First thing disable any Voodoo tools on your phone if any.

      Follow the steps carefully in page 2, if you miss single step it will not be updated.

      Thanks You!

      since its an official update which you tried to update with and it failed, you need to contact the LG Service centre for the same!

    This rom is not Ice cream sandwich – it’s theme!
    And this archive is broken!
    you can find KING_3D_ROM_v2.3 by KING4Developers.
    It’s the most recent ROM for LG 3d.

    I’ve followed all the instructions. My phone is rooted.
    When I run the install rom from SD card, the phone reboots, accesses the ICS rom and then give me:
    Can’t open /emmc/IceCREAMSandwich4.0_for_LGOptimus3D_KingROM.zip
    Installation aborted.

    I have downloaded the rom twice.
    The size of both are 277MB.

    If I try to unzip the rom on my PC it says unexpected end of archive.

    Hi, nothing..my LG 3D doesn’t install THIS ROM so yesterday evening i try to install the famous KING ROM 3D 2.2..and it’s OK !

    how can I upgrade lg p970? or can I use this?

    • NeaL Pradeep

      November 7, 2011 at 2:27 pm

      no, p70 is a different model you cannot apply this procedure!

    November 7, 2011 at 2:23 am

    nothing to do, neither with data+cache & dalvik clean ! :o(

    everything appear to be ok at restart (ok..ok..) then my phone reboot immediately (i think with an error): where can i find LOG file?

    • NeaL Pradeep

      November 7, 2011 at 2:29 pm

      you cannot find the log file!

      • Andrea

        November 7, 2011 at 3:22 pm

        o no…shit ! So i can’t find where is the problem ! 🙁

        What can i do ?

    • Andrea

      November 7, 2011 at 3:25 pm

      i try another time following the procedure : everything appear to go but after few second after my LG 3D “unzip” the ZIP file the phone reboot (i think with an error…)
      Can it depend from my “Vodafone” LG 3D (but with rooted + CWM) ?

      What can i do ?

      • NeaL Pradeep

        November 7, 2011 at 4:13 pm

        its not recommended to update the n/w locked devices!

        • Andrea

          November 7, 2011 at 6:27 pm

          Ciao, mine is unlocked : my network provider now is H3G (3 italia)

        • Andrea

          November 7, 2011 at 7:18 pm

          Ciao NeaL, you appear to be good informed : my LG 3D was Vodafone but i buy it unlocked (Now my network provider now is H3G (3 italia) : what can i do ?

          Its original firmware is really slow, is the worst i ever found…and doesn’t exist the famous very good MIUI for it : i think this is my only chance for now ! =:| :o)

          • NeaL Pradeep

            November 7, 2011 at 11:42 pm

            you can apply this, let us know if you face any issues!
